FEEDER FOR HAY-PRESSES.

SPECIFICATION forming part of LettersPatent No. 790,082, dated May 16,1905.

Application filed July 25, 1904. b'erial No. 218,058. I

To a, whom it may concern.-

Be it known that I, EUGENE W. SHAW, a citi- Zen of the United States,residing at Weir, in the county of Cherokee and State of Kansas, haveinvented certain new and useful Improvements in Feeders for Hay-Presses;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to feeding mechanisms for hay-presses; and it hasfor its object to provide a construction wherein the hay will be fed tothe hopper intermittently in sufficient quantities to form bales and inwhich the entire manipulation of the hay from the time it is supplied tothe feeder until the bale is formed in the baling-chamber ready forbinding will be automatic.

Other objects and advantages of the invention will be understood fromthe following description.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several Views,Figure 1 is a top plan view showing a press embodying thepresentinvention. Fig. 21s a section taken transversely through the press in avertical plane in advance of the baling-chamber, certain of thedriving-chains Fig. 3 is a section similar to. Fig. 2, passinglongitudi- Fig. {1 is a section similar to Fig. .2 at the opposite sideof the feeding mechanism.

Referring now to the drawings, there is shown a common form ofbalingpress, including a base 10, upon which is 'ahousing, includlng abahng-chamber l1 and a runway 12, extendlng therefrom and through whichthe bales are forced. A plunger 13 is employed,

which is operated from a crank-shaft 1 1, provided with a sweep 15 forrotating it. Above the baling-chamber is a hopper 16, transversely ofwhich is journaled a crank-shaft 17, to the crank of which is connecteda-rod 18, having an enlarged base 19, which rod and base form a tramperfor forcing thehay or straw through the hopper and into. thebalingchamber, the length of the crank being suchthat as the shaftrotates the base of the tramper will be raised sufficiently high topermit of passage of material through the side of the hopper beneath thebase of the tramper, and the tramper will then be carried downwardlythrough the hopper and into the baling-chamber to press the material andhold it until the pressing-plunger has engaged it, the tramper risingfrom the baling-chamber as the plun ger enters it. 1 One side of thehopper is open, and communicating therewith is a feeding-chute 20, intowhich the material is first placed and through which it is fed to thehopper. The outer end portion of the feeding-chute has its bottomslotted, as shown at 21, and at the ends of the slots are mounteddouble-crank shafts 22 and 23, the cranks of each shaft being disposedin the bars 24 projects a series of pins 25, which 7 engage the hay orstraw that is placed in the outer end of the chute and urge it in thedirection of the hopper. To-rotate the crankshafts, the sweep 15 isprovided with a horizontal gear 26, which meshes with a gear 27,

on a shaft 28, which extends in the direction of the hopper and which atits end next to the hopper is provided with a sprocket-wheel 27. Astub-shaft 28' is mounted upon the end of the press and carries a pairof sprocketwheels 29 and 30, which are connected for simultaneousrotation. On the shafts 22 and 23 are sprocket-wheels 31 and 32,respectively. A chain 33 connects the sprocket-wheels 27 and 29, and asecond chain 34: connects the sprocket-wheels 30, 31, and 32, so that asthe sweep is carried around the bars 2 1, termed packer-bars, areoperated.

To rotate the crank-shaft 17 and operate the tramper, the shaft 22 isprovided with a sprocket-wheel 35.. with which is engaged a chain 36,which engages also a sprocket-wheel 37, said chain and sprocket-wheelsbeing at the opposite side of the chute from the sprocketwheel 31.

The end of the chute adjacent to the hopper is covered, as illustratedat 37, and at the front and rear edges, respectively, of the cover arejournaled the shafts 38 and 39, carrying sprocket-wheels 40 and 41,respectively, with .which are engaged chains 4-2 and 43,1'espectively,that pass below the cover longitudinally of the chute and then upwardlyand over the cover, as illustrated, and in spaced relation thereto, eachof the chains being provided with fingers 11 of such length as to reachvery nearly to the bottom of the chute as they pass longitudinallythereof as the shafts 38 and 39 are rotated. The fingers are designed tofeed the material to be baled through the covered portion of the chateand into the hopper, and they travel in a corresponding direction. Inorder that these fecding-fingers may act only when the tramper is inraised position with its base above the floor of the chute, the shaft 38is provided with a pinion 15, which is engaged at intervals by the teethof the mutilated gear-wheel 46, which is carried by the shaft 17, theseteeth being so positioned on the gear-wheel that they will engage thepinion during an angular movement of the gear-wheel of approximately onehundred and twenty degrees when the tramper is in raised position. Thuswhen the tramper is in position to permit of passage of material beneathit into the hopper the feeders will be actuated.

With the construction described it will be noted that packers, includingthe rods 24 and the fingers 25, will be continuously operated, but thatthe fingers are so short and operate upon the material in such positionthat comparatively slight resistance to the passage of the material willrender the packers ineffective. To render the packers effective, a gateis provided, comprising a bar 50, from which depend finger's 51 into thechute, the bar being so positioned that the lower ends of the fingersmay lie slightly in the rear of the packers when the fingers are in thechute. From the rod depends a crank-arm 52, to the lower or free end ofwhich is pivoted a rod 53, which extends in the direction of the hopper16 through a guide 54, said rod having at its free end a roller 55. Onthe face of the Wheel 46 is a cam 56, and as the wheel 46 rotates andits teeth move out of engagement with the pinion 45 the cam strikes theroller 55 and by pressing thereagainst forces the rod 53 longitudinally,so as to swing the fingers 51 downwardly into the chute in position toprevent passage of material into the covered portion of the seat forengagement by the feeding-fingers. The cam 56 holds the rod 53 in itsrearward position until the tramper has descended and pressed thematerial down into the baling-chamber and has returned to position topermit of passage of material into the hopper beneath the tramper. Thecam then releases the rod by passing from contact with the roller 55,and the lingers 51 are permitted to swing in the direction of thehopper, so the material to be baled may pass into the covered portion ofthe chute to be engaged by and pass onward by the feeding-fingers.

At the rear of the hopper is an opening 60 in the top of the hopper,which permits of inserting the ordinary block previous to formation ofthe bale. The opening 60 is somewhat wider than the block illustrated at61, and the opening is divided by a cross-bar 62 between the block andthe hopper, and a vertically-movable gate is slidably disposed betweenthe bar and the hopper, the gate being provided with a hand e 6st forraising and lowering it. This gate prevents the loose hay from gettinginto the way of the block during the tramping operation.
